clare ythe following to' be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sliding doors and more particularly to sliding doors for show cases.

An object of the invention is to provide means for preventing the doors from vbecoming accidentally displaced from the tracks upon which they slide while in regular use.

A further object of the invent'Jn is to provide registering notches in the top guides for a pair of doors carrying projecting plns, whereby when the doors are moved-to a position to bring .the pins immediately under the notches, each door may be raised from the track upon which it is mounted and removed from the case.

A further object of the inventionA is to construct the projecting pins in such a way that each may be quickly reduced in size to overcome any pressure thereon, which may be caused by the sagging of the top of the case.

A further object of the invention is to provide a dust proof joint between the doors when each door is in its eXtreme closed position.

With these and other objects in view, the` section taken on line C-C of Fig. 1.

I-Ieretofore sliding doors have been placed in show cases without any means for preventing the accidental lifting of the doors fromA the tracks upon which they were mounted, during their operation lin every day use. The accidental displacement of the doors, due to the operators unconsciously raising the same while'sliding them from one side of the case to the other, has caused av great deal of trouble and annoyance and y, the present invention 4is adapted to overcome such objectionable features. I. do not wish to limit myself to sliding doors for show cases alone, but wish it understood that the invention .is readily applicable to sliding doors for all 'other constructions in which the doorsare likely to be displaced upon their tracks, either by rough handling or otherwise. Y

.Referring to the drawings by numerals, 10 represents the base upon which the show case is mounted. Upon the base 10 is placed a bottom 11 having track members 12 and 13 secured thereon. At the ends of the case are mounted upright frame members 14, to the inside of which are secured abutting members 15. Connecting the frame members 14 and the abutting members 15 at the top of the case, is a supporting member 16,

to which is secured a glass top 17. Secured i door 23,1whic is guided at the top between the two guiding members 21 and 22. Mount` ed upon track 12 is a sliding door 24 which is guided at the top between the guiding members 20 and 21. Each of the doors. 23 and 24 are mounted on rollers 25, which run on the tracks 12 and 13 and support the doors thereon. Secured tothe abutting members 15 are door bearing strips 26 and 27 for engaging the outer ends of the doors, when the same are in a closed position, as shown in Fig. 1.

Mounted at the top of the door 23 is a pair of projecting pins 28 (one of which is not shown) and mountedv at the top of the door 24 is also a pair of projecting pins 29. The pins are made of wood, or some soft material, so that the' tops of the same may be easily trimmed off, if the top of the case sags upon the pins to an amount suiicient to prevent the sliding of the doors. Formed in the bottom edge of the guiding member 21, is a pair of notches (one of which is not shown) which are spaced the same distance apart as the pair of projecting pins 26 to permit of the raising of the doors 23 above the tracks 12 and 13, in order that the same may be removed from the case. Formed in the bottom edge of the guiding member 20, is a pair of notches 31 registering with the notches 30 and spaced the same distance apart as the pair of projecting pins 29, carried by the slldin door 24, so that the door may be raised a ove track 12 and removed from the case. .Both of the doors may be readily removed by sliding the same to a position to cause the projecting pins to come immediately under their respective notches, so that the doors may be raised and the pins on the doors raised into the notches a suiicient distance for the bottom yof the doors to clear the tracks.

In ordinary use the doors are prevented from being accidentally raisedv from the tracks by the pins coming'in contact with the bottom edges of the guiding members 20 and 21.

One of the stiles or each of the doors 'is cut out as at 32 and 33 to provide a con-` venient means for sliding the doors by hand from one side of the case to the other.

ln Figs. 3 and td a beveled strip 34 is shown attached to the inside of the right yhand stile of door 24 and a corresponding beveled strip 35 to the outside of the lefthand stile of door 23. A felt strip 36 is secured to the beveled strip 34.` anda corresponding felt stri 37 1s secured to the beveled strip 35 as s own in Figs. 3 and 4 and for the purpose of forming a dust proof joint betweent e doors.

- What I claim is;

1. In a cabinet, door guiding means secured along the lower side, cleats secured to the upper side of the cabinet in spaced relation also forming'door guides and provided lintermediate their ends with recesses, and doorsfmounted toslide upon the guiding means and provided with studs adapted to engage under the cleats and prevent raising the door but to permit the raising of `the door when the studs register with the recesses.

2. The combination with a cabinet of cleats secured along the upper edge of the cabinet in spaced relation, said cleats being provided with recesses formed in their lower edges, doors mounted to slide between the cleats and provided with studs positioned to engage beneath the lower edges of the cleats and prevent the door being raised, said studs beingA spaced similarly to the spacing of the recesses whereby the doors may be raised when the studs register with the recesses.

1n testimon whereof l aix my signature in presence ot two witnesses.
